1994, 16 pp.
$58.50

Current Methods available for evaluating physical properties of concrete in existing structures to determine its capability of performing satisfactorily under service conditions are identified and discussed. The report recommends project design, operation and maintenance records, and in-service inspection data to be reviewed. Methods for evaluation of test and survey data are presented.
